LAMP-BURNER.

SPECIFICATION forming part of Letters Patent No. 356,968, dated February Ji., 1887.

Application filed April 12, 1886. Serial No. 198,585.

taken in a different plane from that of Fig. l.V

Fig. 3 isa bottoni view. Fig. 4 is a perspective view of a bearingpiece for the rotary shaft, forming part of a wick-adj usting mechanism, and a guide for a rack, which, is comprised in such mechanism.

Similar letters of reference designate corresponding parts in all the figures.

A designates the main shell of the burner. lt has an externally-screw-threaded cylindric base portion,'suitable for engagement with the internally-screw-threaded mouth of an oil reservoir or fount, and a cup-shaped or flaring upper portion, which is perforated so as to admit of the passage of air through it.

A A2 A3 designate an` annular wick-tube consisting of a shell, A', which is affixed to theI main shell A by solder or other means, an upper shell, A2, which is of smaller diameter than the' shell A', except at `the base, where it is adapted to tit into the shell A', and ashell, A3, which extends up through the shells A A2. The shells A A2 form the outer wall of the wick-tube, and the shell A2 isdetachably connected to the shell A', preferably by means of a bayonet-joint. The shell A3 forms the inner wall of the wick-tube and also a central draft-flue. lt is closed at the bottom and secured to the shell Af by means of a flange or strip of metal extending from an opening, o',

which is providedin its lower portion, to a corresponding opening,o2, which is provided opposite to it in the shell A. Air may-pass from the interior of the main s hell A of the burner through the opening o2 of the v shell A just mentioned, and the corresponding opening, o', of the shell A3 into the space o r due within the shell A3. This air will ascend to the inner or in any other suitable manner.

surface of a 'flame emanating from the tip ofa wick-tube. The inner shell, A3, ofthe wicktube is bent at opposite portions to form two longitudinal grooves or recesses, a a, in its exterior. K

B designates a rod, which may be made of sheet metal, channeled, to giveit stiffness, and

bent into such shape as to have two upwardlyextending arms, which fit into the grooves a a? of the shell A3, and an intermediate portion which extends across the bottom of the shell A3. These arms at the upper end are connected to a ring, C, by riveting them thereto," This ring iits snugly around the exterior of theinuer shell, A3, ofthe wick-tube, and is provided with a number of spurs, c, which engage with the wick; consequently, if the ringis moved upwardly or downwardly by means of the rod B,

the wick will be correspondingly moved. The portion of the rod B which extends crosswise ofthe shell A3 of the wick-tube, and between the arms which are attached to the ring C, is secured to a rack, D, which is made of sheet metal, by punching or cutting holes at intervals through the same. This rack engages Witha toothed wheel, E, which is affixed to a rotary shaft, E', that extends through the openings of the outer and inner shells of the wick-tube, whereby air is allowed to pass to the central draft-flue, and also out throughthe main shell A of the burner. The shaft E is supported in a bearing, G, which consists of a piece of sheet metal bent into tubular form, so as to correspond to the exterior of the shaft, and it has formed integral with it a portion, G',.which is bent transversely to the axes of the shaft, so as to form a bearing for the rack l). The guide Gis perforated and bent around so as to fit over the inner end of the shaft E. This combined bearing and guide G G. maybe secured in place by solder or in any other suitable manner to the strip of metal which extends between the openings o o2 in the shells A A3, through which air passes to the central draft-flue.

H is a post or rod, which is supported in a fixed position by means of abridge-piece, H", extending across the inner shell, A3, of the wick-tube.

I designates a button or spreader, which is ICO as large diametrically as the shell A2 of the wick-tube, and may be made of sheet metal. It has a tubular portion, t', which lits the post or rod H loosely, so that the button or spreader may slide freely up and down along said post or rod.

J designates a rotary shaft, which is journaled ina bearing, J', that is secured in place by solder or otherwise. rlhis shaft has outside the main shell A of the burner a hand-piece, J2, by which itmay be partially rotated. At the inner end of the shaft is a crank, j. Connected to this crank is a link, K, which at the upper end is bent so as to tit around the post or rod H. This link, where it surrounds the post or rod H, is beneath the tubular portion of the button or spreader I.

The shaft J, when rotated so that its crank j is in its lowest position, allows the button or spreader to descend upon the tip of the wicktube, so as to act as an extinguisher to the flame. The shaft J constitutes, in effect, a rocking-arm. Then the shaft is rotated in the other direction as far as it can be rotated, the crankj will be in its uppermost position, and will have moved just beyond a vertical line,so that the weight ofthe button or spreader will not cause it to move out ofthat position. The slightest movement of the shaft J will carry the crank y beyond a vertical position in the other direction, and thereupon the weight of the button or spreader will cause it to descend suddenly upon the tip of the wick-tube. The flame will thus be extinguished veryeffectively, and much more so, owing to the sudden descent of the button or spreader, than if it were pulled down by the hand-piece against the resistance of a spring or other counterbalance.

That I claim as my invention, and desire to secure by Letters Patent, is-

l. The combination of an annular wicktube, a vertically-movablebutton 0r spreader, a rocking arm. a crank on said arm, a handpiece outside the burner for rocking said arm, and a connection between the crank and thc button or spreader, substantial] y as described, whereby when the crank is moved by the roek ing arm above said arm and beyond a vertical position in one direction the button orspreader will be supported in an elevated position, and when moved beyond a vertical position in the other direction the button or spreader will fall by gravity.

2. Thecombinationofanannularwick-tube, a post or rod extending up within the inner shell of the same and secured in a fixed position, a button or spreader fitted to said post or rod so that it will slide along the same, aroeking arm, a crank on said arm, a link extending between the crank and button or spreader, and a hand-piece on the rocking arm outside the burner for rocking the same.

3. The combination, with an annular wicktube,ot'a rotary wick-adj usting shaft, E',a rack, D, a carrier connected with the rack, a shaftbearing. G, consisting of a piece of sheet metal bent into tubular form, and a guide, G, formed integral with said bearing and receiving the rack D, substantially as specified.
